BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to medical collecting containers, and more particularly, to fat harvesting containers.

2. Description of the Related Art

Liposuction, also known as lipoplasty, liposculpture suction lipectomy, or simply lipo (suction-assisted fat removal) is a cosmetic surgery operation that removes fat from many different sites of the human body. Since liposuction procedures have become more widely available, fat has also become more easily withdrawn from the body. That development has allowed more plastic, dermatological, and cosmetic surgeons to offer their patients fat transfer for cosmetic reasons. Patients like fat transfer because it is their own tissue and, hence, not subject to rejection by the body. However, the safety of the technique relates not only to the amount of tissue removed, but also to the harvesting of fat to be transferred.

Essentially, the fat transfer procedure harvests fat from one part of the body, where an excess exists, and then places it in another part of the body where the additional bulk is used for cosmetic and aesthetic purposes. Fat transfer, which is also known as fat grafting, fat autographs, autologous fat transplantation, fat injecting, or microlipoinjections, may be used to smooth and repair aged hands; fill wrinkled and creased faces; create more shapely, curvaceous buttocks; or enlarge breasts as an example.

In the most common used procedures, fat is withdrawn from the patient with a syringe that has a large bore needle or with a liposuction cannula. The fat is prepared according to the practitioner's preferred method and then injected into the patient's recipient site. The preparation process needs to clear the donor fat of blood and other unwanted ingredients that could cause undesirable side effects. Moreover, some physicians have found that human fat outside the body is incredibly delicate. An important fact of the survival of injected fat seems to depend on how the physician harvests the donor fat, the technique used to treat the fat, and how the prepared fat cells are put back into the patient. Therefore, the procedure is operator dependent and relies on the techniques of harvesting, cleansing, and reinjection.

In order to prepare the fat tissue for injection, it must be separated from other harvested substances in a mixture, whereby the mixture is manipulated in a variety of ways in order to remove oil and tumescent fluid layers for the transfer of the fat tissue. The transfer of the fat tissue is usually made to smaller transplantation syringes for transplantation. Various manipulation techniques involve rotating and moving the mixture from one container to another. Often, the fat tissue is injected into another container to be washed, and then injected into the smaller transplantation syringes so that it may then be injected into the desired location. Each of these manipulations exposes at least some of the mixture and the fat tissue therein to air. In addition, they bring the mixture and tissue into contact with additional instruments and surfaces, often causing trauma to the tissue. Each exposure to air reduces the viability of the fat tissue, and increases the risk of contamination. Each manipulation of the mixture, and the fat tissue contained therein, affects the results of the transplantation. The compromised sterility increases the chances of inflammation, and rejection of the fat transplant.

Other methods and apparatus related to the subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these methods and apparatus suggest the novel features of the present invention.

SUMMARY OF THE INVENTION

The instant invention is a medical collecting container for harvesting human body fat. More specifically, the instant invention is a fat harvesting container, comprising a container assembly having a first top edge. A funnel structure is within the container assembly. It is noted that the funnel structure can be a separate funnel assembly or may protrude inwardly from an internal face of the exterior wall as a single piece. Furthermore, the funnel structure may rest on an internal base assembly for structural integrity and support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings, the present invention is generally referred to with numeral 10. It can be observed that it basically includes container assembly 20, funnel structure 50, lid assembly 70, and tubing assembly 100.

As seen in FIG. 1, container assembly 20 is preferably made of a rigid and transparent material. In the preferred embodiment, container assembly 20 has a substantially cylindrical tapered shape, wherein the diameter of base 28 is smaller than the diameter of top edge 26. Container assembly 20 comprises exterior wall 22 with measurement indicator 24. Outlet 30 has a substantially tubular shape and is disposed at a first predetermined elevated distance from base 28. This allows the practitioner room to operate valve assembly 40. In the preferred embodiment, valve assembly 40 is a three-way valve and comprises suction inlet 42, suction outlet 44, and syringe outlet 46. Valve assembly 40 is removably mounted onto outlet 30 with suction inlet 42.

Housed within container assembly 20 is funnel structure 50. It is noted that funnel structure 50 can be a separate funnel assembly or may protrude inwardly from an internal face of exterior wall 22 as a single piece. Furthermore, funnel structure 50 may rest on an internal base assembly for structural integrity and support. Funnel structure 50 comprises top edge 52, aperture 54, sidewall 56, and connecting line 58. Funnel structure 50 is cooperatively disposed at a second predetermined distance from base 28 to allow connecting line 58 to align with outlet 30. Although not illustrated, funnel structure 50 may rest upon a solid or semi-solid base structure within container assembly 20, extending from base 28 to funnel structure 50.

Lid assembly 70 is preferably made of a semi-flexible material. Lid assembly 70 comprises top wall 72 having outlet post 74 and inlet post 76, and sidewall 78. Although not required, lid assembly 70 may also comprise lip 80. Although not seen, lid assembly 70 also comprises a circular channel that aligns with to receive top edge 26 when lid assembly 70 is placed upon top edge 26 with a predetermined force to hermetically seal container assembly 20.

Tubing assembly 100 comprises suction tube 102, outlet tube 106, bypass tube 108, inlet tube 110, and valve assembly 120. Suction tube 102 is connected to a vacuum pump liposuction machine, not shown, at a suction tube 102 first end, and to valve assembly 120 at a suction tube 102 second end. Valve assembly 120 also receives an outlet tube 106 first end, and a bypass tube 108 first end. An outlet tube 106 second end connects to outlet post 74, and a bypass tube 108 second end is connected to suction outlet 44. An inlet tube 110 first end connects to tooling to obtain matter from a patient. Such tooling can be a syringe, not shown. An inlet tube 110 second end connects to inlet post 76. Although not illustrated, it is noted that tubing assembly 100, including suction tube 102, outlet tube 106, bypass tube 108, inlet tube 110, and valve assemblies 40 and 120 may comprise luer locks or similar locking and/or fastening systems.

As seen in FIG. 2, during a liposuction procedure, matter; defined as emulsion E, containing liquid matter LM and fat matter FM, seen in FIG. 3, is vacuumed from a patient through inlet tube 110 and into container assembly 20. Vacuum pressure is created within container assembly 20, inlet tube 110, and the syringe by the vacuum pump liposuction machine connected to suction tube 102. It is noted that in some cases, the matter, defined as emulsion E, may also comprise blood and blood tissue, and other emulsion fluids. Emulsion E may also comprise chemical compositions or solutions such as saline that are typically used by the plastic, dermatological, and cosmetic surgeons, also defined as practitioners, to improve the process of fat harvesting, whereby saline is first introduced or injected into the patient before the liposuction procedure. Although not illustrated, it is noted that in the event of large displacements of emulsion E during a liposuction procedure, emulsion E may be discarded through bypass tube 108. Such an event occurs if the capacity of container assembly 20 is not sufficient for emulsion E. In that case, valve assembly 40 is operated to open suction outlet 44 to allow emulsion E to be discarded through bypass tube 108. If necessary, valve assembly 120 may be operated to close outlet tube 106, thus creating greater vacuum pressure within bypass tube 108. Alternatively, valve assembly 120 may be operated to also open outlet tube 106, thus adjusting vacuum pressure within bypass tube 108.

As seen in FIG. 3, after the liposuction procedure is complete, a natural separation of liquid matter LM from fat matter FM occurs within container assembly 20 after a first predetermined time period. The natural separation occurs because fat matter FM is lighter than liquid matter LM, blood and blood tissue, and chemical compositions or solutions such as saline. After the first predetermined time period, valve assembly 40 is operated to open suction outlet 44 to allow liquid matter LM, blood and blood tissue, and chemical compositions or solutions such as saline to be discarded through bypass tube 108, whereby vacuum pressure is created within bypass tube 108 by the vacuum pump liposuction machine. If necessary, valve assembly 120 may be operated to close outlet tube 106, thus creating greater vacuum pressure within bypass tube 108.

As seen in FIG. 4, after liquid matter LM, blood and blood tissue, emulsion fluids, and chemical compositions or solutions such as saline are discarded through bypass tube 108, the practitioner operates valve assembly 40 to open syringe outlet 46 so that syringe S, as a transplantation syringe, can be used to withdraw a desired amount of fat matter FM therefrom, to then introduce or inject it into the desired location of the patient.

Instant invention 10 therefore safely harvests the human body fat defined as fat matter FM, whereby it minimizes exposure to air and bacteria to reduce contamination risks. Instant invention 10 improves the viability of fat matter FM, whereby it minimizes manipulation of emulsion E contained therein. Furthermore, instant invention 10 maximizes sterility of emulsion E and specifically fat matter FM, during a fat collection and preparation process, so that the fat matter FM can be introduced or injected into the desired location of the patient.
